I'm not in the UK but if you check rankings on Alexa Google definitely higher than bing, which I find unfortunate as bing is a very nice search engine that's better than Google on some fronts.
Bing is surely getting top search engine. Let google keep updating there algorithm while we all people transfer to Bing
According to research by Forrester I believe, Google has a higher % of the UK market than US. UK currently sits at 90% for Google.
In UK I think its Google. Earlier I was solely using Google search but now I use both Google and Bing. Don't underestimate Bing. They already have a 30% US market share and getting popular day by day.
That is why I am wondering how Bing and Yahoo still get such decent numbers still. You would think that Google would take all of the users.
